Biodiesel is renewable and environmental friendly fuel which has the potential to obtain considerable performance of engine. The aim of this work is to optimize the transesterification process for production of biodiesel using Taguchi method. In this experimental work, the Karanja oil transesterification is done to produce biodiesel using Al2O3 as a heterogeneous catalyst, using five parameters and five levels. Orthogonal array obtained by Minitab to analyze the interaction effect by using Taguchi method for the transesterification reaction. The parameters such as molar ratio of methanol to oil, catalyst concentration, reaction temperature, reaction time and stirring speed are effect on biodiesel yield. Effect of these parameters is investigated on small scale. Experimental yield obtained at optimal conditions i.e. are 20:1 molar ratio of methanol to oil, addition of 3% Al2O3 catalyst, reaction temperature 65ºC, reaction time 60 min and 600 rpm stirring speed is 80%.


Biodiesel is renewable and environmental friendly fuel which has the capable to gain comparable engine performance. In this experimental study, Karanja oil synthesized by using Transesterification process. Transesterification of Karanja oil to biodiesel using SiO2 as a heterogeneous catalyst is studied using five different parameters and levels each. Minitab is used to fix the orthogonal arrays and Taguchi method is used to analyze the interaction effect for the transesterification reaction. The five different parameters responsible for biodiesel yield are molar ratio of methanol to oil, catalyst concentration, reaction temperature, reaction time and stirring speed. Effect of these parameters has studied on small scale. The biodiesel yield obtained experimentally at optimum conditions are 20% methanol to oil molar ratio, 3% SiO2 catalyst addition, 65ºC reaction temperature, 180 min reaction time and 500 rpm stirring speed is 77%.

<p>Sodium aluminate is presented as a highly active heterogeneous catalyst able to convert a range of alcohols into the corresponding mixed carbonate esters, in high yield and under green conditions. The reaction is carried out using dimethyl carbonate both as a reactant and solvent, at 90°C. Allylic, aliphatic and aromatic alcohols are converted in good yields. The solid catalyst is shown to be truly heterogeneous, resistant to leaching, and recyclable. </p>

Abstract:: Mesoporous silica nanomaterials provide an extraordinary advantage for making new and superior heterogeneous catalysts because of their surface silanol groups. The functionalized mesoporous SBA-15, such as acidic, basic, BrÖnsted, lewis acid, and chiral catalysts, are used for a wide range of organic synthesis. The importance of the chiral ligands, which were immobilized on the SBA-15, was mentioned in this review to achieve chiral products as valuable target molecules. Herein, their synthesis and application in different organic transformations are reviewed from 2016 till date 2020.
